BENJAMIN G. BUTLER, OF COLUMBIA, SOUTH ICE-CREAM FREEZER.

No. 878,709. Specification of Letters Patent. Patented Feb'. 11, 1908. Application filed March 28. 1907. Serial No. 364.991. To all whom it may concern: used, if desired, as an ordinary refrigerator or ice box. The lid 5 is rabbeted as shown so as to snugly fit wit 'n the box 1, and -a packing strip 6 fits within the rabbeted portion so as to render the device air tight. The lid may be provided with any form of lock, such as the ordinary snap lock illustrated in the drawings;

. The endsof the box are formedon their inner walls with opppsing'f-ertically extending -recesses.8 iniw Glr'tl'k, freezing cans 9 are adapted to be slipped so as to stand on end the box spaced relation-to each other, with freezingmaterial-filling the them. T-he opposite sides Be it known that I, BENJAMIN G. BUTLER, citizen of the United States, residing at Columbia, in the county of Richland and 5 State of South Carolina, have invented certain new and usefullmrovements in Ice- Cream Freezers, ofwhic the following is a specification. I

This invention contemplates certain new 10 and useful improvements in that type of ice cream freezer which is adapted to efle ct freezing of cream by a rocking motion, and the-invention-consists in certain constructions and arrangements of the parts.herein after described and claimed, whereby asim a ple, cheap, durable, and efficient construction of freezer is produced.-.-

For a full understanding of the invention and the merits thereof and also to-acq uire a knowledge of the details of constructlon of vided-"at its u per sideaedges wintsimilar the means for effecting the'result, reference stri s 12,- so t A l i is to be had to the following description aild reagl accompanying drawings, in which operation has been completed.

Figure 1 is a perspective viewof my im-" proved ice cream freezer;-Fig. 2 is a transverse sectional view thereof; .Fig. 3 is a detail perspective view of one of the freezingz-cans;

ig'. 4- is a detail perspective and detached view of one of the latch bars and its locking plates; Fig. 5 is spaces between aced reinforcing strips iron or the like, and the adapted to slip snugly over cover 11 which is ner face of one'-side:of the box, and opposing plates 14 are secured to the opposite side, each plate 13 beingformed with a recess and the "opposing plates with a" bayonet slot. Bars 15 are adapted'to have one end slipped into a slot lying within the marginof the respective plates 13, the othef ends of said bars being designed to be slipped dcwnardly into the bayonetfslots of the plates 14 and adapted to beheld therein by gravity or other forms of latches 16, so as to extend entirely across theiseries of freezing cans 9 and hold them securely in place during the rocking, movement, as well as assisting in maintaining the lids or covers 11 of the respective a detail perspective view on areduced scale of the packing box that may be employed in connection with the freezer; Fig. 6 is a detail erspective view of the division block; an Fig. 7 is' -.a detail'fragmentary view on an enlarged scale of one of the-legs of the brace employed to holdthe freezer as against its rocking movement.

Corresponding and like parts are referred to in the following description and indicated 40 in all the views of the drawings by the same reference characters.

A box or receptacle 1 constituting the body ofthe freezer hasits opposite sides extending downwardly to form rockers 2 .that

are preferably rovided on their edgeswith corrugated rubber strips 3 adapted'to render the device noiseless in its operation and to assist in preventing any creeping motion of the device along the floor or other support upon which the device is actuated. The interior walls of the box 1 as well as the lid '5,- which is hinged, are provided with metallic s that 1 are referably spaced 'somewhat-from the woo work of which the structureis composed so that the de 'ce-ma'y be cans.

While the box 1 may be rocked by any desired mechanical means, I have, inythe present instance shown forthis purpose, one ormore endhandles lZ-and a side knob on handle 18 by whichthe freezer may'bemanw ally operated.

In the event that it, is desired to utilize less .than the full capac'ty of the freezer, I provide a division block 19 which isadapted to slip downinto any pair of grooves or re- ,ccsses. .8 so as to divide the box into compartments. The division block 19 1S provlded locking filled. and

placed -.intherecesses and locked of 'eadh can are preferably provided-with i 10- of galvanized the-box is prot 'theil' P o r; may ibt y lifted from the can af h .3

Qne or more plates 13 are secured to thenn'f with slots 30 adapted to accommodatethe 7 .bars 15. -After the cans have been 1 cans 9 are then therein and packed around with a freezing mixture, the lid 5 is closed and the box rocked back and forth until the freezing operation has been completed. The freezer removed from the box and. the frozen slabs are taken out and cut preferably into blocks. The blocks, as is customary, are wrapped in paraffin or similar paper and may be deposited in the covered box 21 and replaced within the receptacle or body of the freezer and packed around with ice so as to be stored away until it is desired to use them.

designates an orifice through which the water may be drained off whenever desired. To hold the box 1 firmly and prevent it from rocking, while it is being filled with or emptied of its contents, I provide a brace 22 consisting of two downwardly extending legs 23 connected by a horizontal cross bar, as shown, and lying against the side of one of the rockers. Each leg 23 is formed with a vertically elongated slot 24 having an upwardly facing socket 2-5 and a downwardly facing socket 26 formed in lateral, branches of the said slot. The rocker is provided with two headed studs received in the respective slots 24 so that the operator by grasping cross bar of the brace, may move the same down and up so that the pins will lodge in the upwardly facing sockets 25 and hold 'the lower ends of the legs projected from the edge of the rocker into contact with the floor or so that the said studs will lodge in the downwardly facing sockets 26 and thereby hold'the brace in the retracted position.

From the foregoing description in connection with the accompanying drawings, it will be seen that I have provided a very simple and efficient construction of ice cream freezer of the character herein set forth, which will be cheap to manufacture and durable, and which may be readily adjusted so as to be held firm against any rocking movement while it is being filled or emptied and in which, also, the freezing cans may be slipped easily in place and as readily removed, said cans being securely held within the freezing box by means of easily operated latch bars.

It will be noted that the recesses 8 are joined at their lower ends by horizontally extending depressions or channels adapted to receive the bottoms of the cans, so that the cans will be supported firmly against any side pressure.

It is to be understood that my invention is applicable to churns as well as to the opera tion of making ice cream, as the same rocking motion, performed by the construction and operation of parts herein disclosed will be the handle or finger piece 28 of the found exceedingly useful inthe operation of transforming milk and cream into butter.

Having thus described the invention, what is claimed as new is:

1. A freezer of the character described,

consisting of a box provided with recesses for the reception of freezing cans, freezing cans adapted to be slipped down into the recesses, a plate secured to the inner face of one side of the box and having'an opening formed therein, another plate secured to the inner face of the opposite side of the box and formed with a bayonet slot, a locking bar, one end of which is adapted to be slipped down into the bayonet slot, and a latch mounted upon the plate with the bayonet slot and adapted to extend over the adjacent end of the locking bar.

2. A freezer of the character described, embodying a box and a lid therefor, the box being provided with rockers, and a brace adapted to hold said box as against a rocking movement, said brace including a pair of downwardly extending legs formed with slots and oppositely facing notches, and a rocker of the box being provided with headed studs accommodated in said slots and ada ted to rest in the respective notches thereo 3. A freezer of the character described, comprising a box and a lid, the box being formed with rockers, and a brace adapted to hold said box as against a rocking movement, said brace embodying jecting legs and a cross bar connecting the same, the legs being formed with vertical slots, and with upwardly and downwardly facing sockets communicating with said slots, and a rocker of the box being provided with headed studs accommodated in said slots and adapted to lodge in the said sockets whereby to hold the brace projected from the lower edge of the rocker or a retracted position with res eot to said edge.

4. A eezer of the character described,

' comprising a box formed with oppositely fac-- ing recesses in its inner wall, said recesses being adapted to receive freezing cans, and a division block adapted to be slipped down into any pair of recesses whereby to divide the box into compartments, the said block being formed with a transverse slot and a locking bar adapted to extend through said slot and arranged for detachable enga ement with opposite sides of the box, as an pose set forth. v

In testimony whereof I affix mv signature in presence of two witnesses.
